    摘要： A game console determines if a hard disk drive is authorized for use with the game console by analyzing an encrypted certificate. The encrypted certificate is stored in memory of the drive. Upon detection of the drive, the game console receives the encrypted certificate and decrypts it. The certificate contains parameters relating to the drive, such as the drives serial number, model number, memory capacity of the drive, and a trademark indicative of the drive's authenticity, for example. The game console also receives these parameters from the drive in unencrypted form. The parameters extracted from the encrypted certificate are compared with the parameters read from the hard disk drive's memory. If the parameters match, the drive is determined to be authentic. The certificate is encrypted with the private key of a public-private key pair and decrypted with the corresponding public key in accordance with well known public-key cryptographic techniques.

    摘要： Copy-protected optical disk format, optical disk recording apparatus for creating disks having such formats and optical disk reading apparatus for reading disks having such formats and for determining whether the disks are authentic. In one aspect, an authentic optical disk has data bit indications along a spiral centerline of the disk, and these data bit indications define a radial wobble which has substantially greater energy at a predefined frequency f.sub.CPW (such as f.sub.CC /392) than at a frequency of f.sub.CC /196, where f.sub.CC is the spatial channel clock frequency. In another aspect, an authorized optical disk has data bit indications along a substantially spiral centerline of the disk, according to a channel clock whose frequency varies across the disk. The disk further has stored thereon an indication of the number of such channel clock cycles which occur along a predetermined test segment of the centerline, optionally together with a pointer to the test segment. Since normal data stream copying techniques do not copy the exact channel clock rates on the disk, and since the copying equipment will inherently introduce its own channel clock variations across the resulting disk, the predetermined test segment on the copy will not have the number of channel clocks as that specified by the data indicating the number of channel clock cycles to expect along the test segment.
